GUARD DEVICE.

Tocll whom it may concern: Be it lmown that I, THOMAS E. MURRAY,

-a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented a certain new and useful Improvement in Guard De- .on the line as, w of Fig.3.

vices, of which the following is a specification. s

The invention is a guard device, comprising a shell constructed intwo parts'so as to be applied to the object to be protected and to inclose the same, the said parts then being secured together by an unreleasable latch fastening. The device can not be removed from the object 'without mutilation of shell or fastening, and hence revelation of any undue access or tampering. v

In the accompanying vdrawingsFigure 1 is a section of theshell in open position, on the line y, y of Fig. 2. Fi 2 is a section I ig. 3'is a section of the shell in closed pos1tion, on the line y, y' of Fig. 2. Fig.4 shows almodifie'dform of the device in which the hinge is re placed by a second latch. Fig. 5 shows the -device applied as a seal fastening. Fig. 6

. shows it applied-as a guard to revent access to a nut, and Fig. 7 shows "it similarly applied to a bottleneck to prevent access to the stopper. In Figs. 6 and 7, one wall of the shell has anopening .to r eceiv e the.shankofthe nut or neck of the bottle, as also indicated in Fig, 2'. Fig; 9 is a perspective view showing the shell with an opening in one wall, and notches in one or both of the edges of theiopp'osite wall to'receive a staple as Similar shown in'Fig. 8, which is a perspective view of staple and hasp with the guard device in place. Fig. 10 shows the device applied as a guard to a pipe union, both walls in this case having openings to receive the pipe.

parts.

The shell 1, preferably 1n flattened spherl- 'cal form, stamped or otherwise sha ed from a single piece of thin metal, is ma e 1n two placed and locked-upon the'staple 20, after parts of the shell may-be provided with notches, asshown at 5, Fig. 9. Part 3 of the shell is flanged over. at the meeting edge,

as shown at 6, and said flanged over part has a slot or eye 7 to receive a spring hook or catch 8, formed at the corresponding portion of part 2. When the parts of the'shell are brought together, the hook 8 passes Specification of Letters Patent. Application filed March 20, 1911.

through the eye 7, thus becoming. compressed, and when the end of the hook clears 1t springs'outwardly and gets a locking part 3 of the shell upon part 2. Said parts then cannot be out cutting off the hinge 4, reaking open the fastening or mutilating the shell, which, of course, at once reveals the fact that the device has been tampered with. Instead of se arated, withconnecting the parts 2, 3 by a hinge 4 and a hook 8, I may unite themby two similar hooks 8, 10, locking'into eyes in flanges 6, 11, either hook then acting as a.hinge, or both being detached when the parts are wholly separated.

My mvention is susceptible of many useful' applications, illustrated. I In Fig. 5, it, is shown applied as a seal fastening For this purpose, two small openings 12 are made in part 2 of the shell, through which the sh ackle wire 13, passing through the-eyes 15, 16 to be connected, is

some of which are here inserted: the ends of said wire being twisted together (as shown in dotted lines) inside the shell. After the wire has been inserted and twisted, the parts of the shell are brought together and locked, in the manner described. It is then impossible to get at the'twisted parts of the wire or to separate the eyes 15, 16, without cutting the shackle wire 13 or mutilating the shell.

- In Figs. 6 and 7, the device is shown applied to a nut 17 and to a bottle neck 18. Here, a semi-circular opening 19 is made in part-2, 3, said openings meeting to form a circular opening, when the parts of the shell are locked together, which circular opening then incloses the shank on the nut, or the neck of the bottle, -Ac'cess eannotjthen be had-to the nut or to the bottle stopper until the shell is removed, whichyas before, cannot be done, without mutilating it.

In Fig. 8, the shell shown in Fig. 9 is the hasp 21 has been adjusted thereon, the notches 5 in the meeting edges of the parts 2, 3 then receiving the legs of the staple. The hasp cannot be taken from the staple,

without mutilatiug the shell. Semi-circular openings, similar-to 19, may be made in both walls of the shell, so that said shell may be applied to a pipe and locked. Thus, in Fig. 10, the shell, thus constructed, incloses a pipe union 22, so that it is im ossible to reach the. same without mutilatlon of the shell, as before. A

It is to be understood that in all the modifications of my device shown in the drawing, the unreleasable latch fastening within the shell comprismgaspring hook on one of the parts and an eye on the other part receiving and engaging said hook, is present.

I claim:

A guard device comprising a shell divided into two flexibly tonnected parts and having a suitable opening or openings in its wall whereby it may be applied to the objeet'to be guarded so as to inclose the same, and an unreleasable latch fastening within said shell comprising a spring hook on one of said parts and an eyeon the other part receivingand engaging said hook.

In testimony whereof I have affixed my signature in presence of two witnesses.
